Output destinations

Various server DD statements are used to address system output such as, console output, trace output, and dump output.

Since WebSphere® Application Server controllers and servants are z/OS® started task address spaces, they can produce a variety of output:
This output can be written to a variety of destinations:

Starting with Version 8.0.0.6, you can also use the redirect_server_output_dir WebSphere environment variable to redirect output to files on the Unix Systems Services (USS) file system. The value specified for this variable is the absolute path of the existing directory that contains the files to which you want output redirected. If a value is not specified for this variable, output continues to be directed to DD statements. Refer to the topic Application server custom properties for z/OS for a description of how to specify a WebSphere environment variable.

If you decide to use USS redirecting, the new file naming scheme for standard output and standard error is as follows:
cellName.nodeName.serverName.jobName.jobId.asType.date.time
followed by either .SYSPRINT.txt or .SYSOUT.txt respectively.
You can use the ROLL_LOGS parameter of the modify command to automate the use of the redirect_server_output_dir. When you issue the following modify command, a new set of ouput files is created for the specified server and its respective servants. Messages are then appended to the end of the previous output file and the beginning of the new file, thereby linking them together.
f <server>, ROLL_LOGS
